The Development of Instruments to Measure Student Mathematical Logical Thinking Ability in Kapita Selekta

Abstract

The ability of logical thinking mathematically is one of the goals of the learning of mathematics, namely forming ability of reasoning students that reflected his skills in critical thinking, logical, systematic, and objective nature, honest, discipline in solving a problem well in various fields. In addition math can form a mindset into a mindset of mathematical, logical, systematic and critical that can be used to solve problems in daily life. This research aims to develop a test instrument for measuring the ability of logical thinking mathematically students on kapita selekta. The development method used in this research is to include: (1) define the variable; (2) outlines the variables into a more detailed indicators/dimensions; (3) draw up the details; (4) perform validation; (5) conducting trials; (6) analyze of validity and reliability. Based on the results of the test in theoretic instruments that developed included into the category is valid and worthy to be used on next stages as an instrument to measure the ability of logical thinking mathematically.
